Comment (by windowsair):
Hi, thanks for your quick reply!
As per your instructions, I tested different color spaces and some of the
results are as follows:
yuv420, yuv422, yuv444: Consistent with the original results.
yuv420p10, yuv422p10: Not the result of alpha premultiplied, the result is
the same as using alpha straight.
It's a little weird.
